摘　　要：数字经济作为经济发展的新动能,正成为中国经济绿色发展的重要支撑。文章基于2011—2021年中国281个地级及以上城市的面板数据,综合利用空间杜宾模型、广义矩估计和中介效应模型对数字经济和城市绿色发展之间的关系进行实证检验,结果显示:(1)数字经济与本市绿色发展水平之间存在显著“倒U”型关系,而与邻近城市绿色发展水平之间存在显著“U”型关系,该结论在以历史上固定电话普及率和滞后期工具变量进行检验后仍然成立;(2)技术创新和资源错配是数字经济影响城市绿色发展的重要传导渠道;(3)数字经济对城市绿色发展的影响存在显著的空间异质性,数字经济对城市绿色发展的影响在平坡和缓坡地区更显著,而在陡坡地区的影响还未充分彰显。数字经济作用效率的空间异质性还体现在区域位置上,数字经济对东部和中部地区城市绿色发展水平的影响显著,而对西部地区城市的影响不显著。As the core driving force of economic development,digital economy is becoming an important support for China’s green economic development.Based on the panel data of 281 cities at prefecture level and above in China from 2011 to 2021,this paper empirically tests the relationship between digital economy and urban green development by using SDM,GMM estimation and mediation effect model.The results are shown as follows:(1)There is a significant inverted U-shaped relationship between digital economy and local green development,while there is a significant U-shaped relationship between digital economy and the green development level of neighboring cities.This conclusion is still valid after the historical fixed telephone penetration rate and lagging instrumental variable test.(2)Technical innovation and resource misallocation are important transmission channels for digital economy to influence urban green development.(3)The impact of digital economy on urban green development has significant spatial heterogeneity,and the impact of digital economy on urban green development is more significant in flat and gentle slope areas,while the impact of steep-slope areas has not been fully demonstrated.The spatial heterogeneity of the efficiency of digital economy is also reflected in the regional location.The impact of digital economy on the green development level of eastern and central cities is significant,while the impact on the western cities is not significant.
